Why This Matters

Speed isn't just about running fast—it's the product of multiple trainable qualities that you need to understand for the CSCS exam. When you break down sprinting performance, you're really looking at force production, rate of force development, neuromuscular coordination, and energy system efficiency. Each drill in your programming toolkit targets specific links in this chain, and knowing which drill addresses which quality separates effective coaches from those who just make athletes tired.

The exam will test your ability to match drills to training goals, sequence them appropriately within a session, and understand the underlying physiological mechanisms. Don't just memorize drill names—know what adaptation each drill produces, what phase of speed it targets (acceleration vs. maximum velocity vs. speed endurance), and how to progress or regress based on athlete needs.


Acceleration-Focused Drills

The acceleration phase (first 10-30 meters) depends on horizontal force application and powerful triple extension. These drills train athletes to overcome inertia and generate maximum ground reaction forces at low velocities.

Acceleration Sprints

  • Targets the drive phase—emphasizes forward lean, aggressive arm action, and powerful ground contact during the first 10-30 meters
  • Develops horizontal force production through repeated practice of the acceleration pattern where ground contact time is longest
  • Key coaching cue: athletes should feel like they're "pushing the ground away" rather than reaching forward with the lead leg

Hill Sprints

  • Natural overload for acceleration mechanics—the incline forces forward lean and eliminates overstriding without coaching intervention
  • Builds posterior chain strength in the glutes and hamstrings while simultaneously training the acceleration motor pattern
  • Ideal grade is 5-15%; steeper hills shift the training effect toward strength and away from speed-specific adaptations

Resisted Sprints (Sled Pulls, Parachutes)

  • Increases force output requirements by adding external load during the acceleration phase, enhancing rate of force development
  • Load selection matters: keep resistance under 10% velocity decrement to maintain speed-specific mechanics
  • Sled pulls offer consistent resistance while parachutes provide variable resistance that increases with velocity—choose based on training goal

Compare: Hill sprints vs. resisted sprints—both overload acceleration, but hills are self-limiting (athletes naturally adjust effort) while sleds allow precise load manipulation. For FRQs on exercise selection, hills work better for large groups; sleds are superior for individualized programming.


Neuromuscular Power Drills

These drills enhance the stretch-shortening cycle and train fast-twitch motor unit recruitment. The goal is maximizing force in minimal ground contact time—the foundation of explosive speed.

Plyometric Exercises (Box Jumps, Depth Jumps)

  • Train the stretch-shortening cycle—rapid eccentric loading followed by explosive concentric action mirrors the demands of sprinting
  • Depth jumps specifically target reactive strength with drop heights typically 30-75 cm based on athlete training status
  • Ground contact time is the key metric: if contacts exceed 0.25 seconds, reduce box height or regress the exercise

Sprint Technique Drills (High Knees, Butt Kicks, Skipping)

  • Isolate specific sprint mechanics for deliberate practice—high knees target hip flexion, butt kicks address hamstring recovery speed
  • A-skips and B-skips integrate multiple components and should progress from slow-controlled to fast-reactive execution
  • Best used in warm-ups to prime movement patterns before high-intensity work, not as primary speed developers

Compare: Depth jumps vs. A-skips—both train reactive ability, but depth jumps develop raw power output while skips refine coordination and timing. Use plyometrics to build the engine; use technique drills to improve efficiency.


Maximum Velocity Drills

Once acceleration ends (typically 30-60 meters), athletes enter the maximum velocity phase characterized by upright posture, shorter ground contacts, and cyclical leg action. These drills target top-end speed qualities.

Flying Sprints

  • Isolate maximum velocity mechanics by using a gradual build-up zone (20-30m) before the timed sprint section
  • Removes acceleration demands so athletes can focus entirely on maintaining upright posture and rapid leg turnover
  • Excellent diagnostic tool: if flying sprint times are good but acceleration is slow, prioritize force production work

Overspeed Training (Downhill Running, Assisted Sprints)

  • Forces stride frequency above normal capacity—trains the nervous system to fire faster through supramaximal velocity exposure
  • Downhill grades should stay under 3% to avoid excessive braking forces and altered mechanics
  • High neural demand and injury risk require full recovery between reps and limited volume (4-6 reps maximum per session)

Compare: Flying sprints vs. overspeed training—flying sprints let athletes practice max velocity at their current capacity, while overspeed pushes beyond current limits. Flying sprints are lower risk and higher volume; overspeed is a specialized tool for advanced athletes with excellent technique.


Agility and Coordination Drills

While not pure speed work, these drills develop neuromuscular coordination, proprioception, and reactive ability that transfer to sport-specific speed demands.

Ladder Drills

  • Primary benefit is coordination, not speed—improves foot placement accuracy and rhythm at submaximal intensities
  • Best used in warm-ups or active recovery rather than as primary speed development tools
  • Common programming error: treating ladder work as conditioning—keep sets short (5-10 seconds) with full recovery

Agility Cone Drills

  • Train change-of-direction ability which requires deceleration strength, body control, and re-acceleration capacity
  • Closed drills (pre-planned patterns) develop movement efficiency; open drills (reactive) train decision-making under speed
  • Sport-specific design matters: angles, distances, and movement patterns should reflect game demands

Compare: Ladder drills vs. cone drills—ladders emphasize linear foot speed and coordination in a fixed pattern, while cones train multi-directional movement and body control. Neither replaces sprint training, but both support overall athleticism.


Energy System Development

Speed training requires appropriate energy system support. These drills bridge the gap between pure speed work and metabolic conditioning.

Interval Training

  • Manipulates work-to-rest ratios to target specific energy systems—short sprints with long rest (1:12-1:20) for alactic power; longer intervals for glycolytic capacity
  • Intensity must remain high to qualify as speed work; if velocity drops significantly, extend recovery or end the session
  • Aerobic base supports recovery between high-intensity efforts and across training sessions

Compare: Acceleration sprints vs. interval training—acceleration work develops the motor pattern and force production (neural/mechanical), while intervals develop the metabolic capacity to repeat efforts. Both are necessary; sequence acceleration work before intervals within a session.

Self-Check Questions

  1. An athlete has excellent flying sprint times but slow 10-meter acceleration. Which two drills would you prioritize, and what physiological quality do they target?

  2. Compare depth jumps and A-skip drills: what training adaptation does each primarily develop, and where would each fit in a training session?

  3. A coach wants to use overspeed training with a high school athlete. What two prerequisites should be in place before implementing this method, and what safety parameters would you set?

  4. If an FRQ asks you to design a speed session for a soccer player, which drills from this list would you include and in what order? Justify your sequencing based on neural demands.

  5. Explain why ladder drills are often misused in speed programs. What is their appropriate role, and what would be a better drill choice if the primary goal is improving maximum sprint velocity?
